Crypto’s crime-tracking giant restores its main tools after hackers exposed every user’s login data
Chainalysis restored Reactor, KYT and Address Screening by Nov. 7 after a security incident exposed user IDs, names, usernames, email addresses, role labels, password hashes and live login tokens for all users. The exposure does not prove every account was accessed. The company said abnormal activity led it to take services offline and that it was notifying customers whose KYT accounts appeared to have been accessed. Investigations API and Rapid Lookup remained under maintenance on Nov. 9. Customers were told to reset passwords, rotate applicable API keys and provide trusted IP addresses before access was restored. Chainalysis said it had no evidence investigation data was accessed or attribution data manipulated; its investigation continued.
